Abstract

SE PRESENTA UN SENSOR DE POSICION MEDIANTE PULSACION ACUSTICA EN EL CUAL UN TRANSDUCTOR ACOPLADO AL LADO DE UN SUBSTRATO IMPARTE UNA ONDA TRANSVERSAL AL INTERIOR DEL SUBSTRATO PARA SU PROPAGACION A LO LARGO DE UN PRIMER EJE. UNA MATRIZ REFLECTORA SE DISPONE A LO LARGO DEL PRIMER EJE PARA REFLEJAR PARTES DE LA ONDA TRANSVERSAL A LO LARGO DE UNA PLURALIDAD DE LINEAS PARALELAS QUE SE EXTIENDEN A LO LARGO DE UNA SUPERFICIE DE PULSACION DEL SUBSTRATO HASTA UNA SEGUNDA MATRIZ REFLECTORA CUYO EJE ES PARALELO AL EJE DE LA PRIMERA MATRIZ REFLECTORA. UNA SEGUNDA MATRIZ REFLECTORA REFLEJA LAS ONDAS TRANSVERSALES INCIDENTES A LA MISMA HASTA UN TRANSDUCTOR MONTADO EN EL LADO DEL SUBSTRATO Y QUE RESPONDE A LAS ONDAS TRANSVERSALES PROPAGADAS HACIA EL MISMO SUMINISTRANDO UNA SEÑAL REPRESENTATIVA DE ESAS ONDAS TRANSVERSALES. UNA PULSACION SOBRE EL SUBSTRATO DA COMO RESULTADO UNA ABSORCION PARCIAL DE LA ENERGIA EN LA ONDA TRANSVERSAL SUFICIENTE PARA PRODUCIR UNA PERTURBACION EN LA MISMA QUE SE MIDE PARA DETERMINAR LA POSICION AXIAL DE LA PULSACION SOBRE EL SUBSTRATO. EN UNA SEGUNDA CONFORMACION SE SUMINISTRA UN TRANSDUCTOR SIMPLE Y UNA MATRIZ REFLECTORA PARA CADA EJE, EN EL QUE VA A DETERMINARSE UNA COORDENADA. EN UNA TERCERA CONFORMACION SE SUMINISTRAN UN TRANSDUCTOR SIMPLE PARA TRANSMITIR Y RECIBIR ONDAS TRANSVERSALES QUE SE PROPAGAN A LO LARGO DE LINEAS PARALELAS PERPENDICULARES.
